Improvement in water-elevators



UNITED NSTATES ALVEUS J. CLEMMONS, OF ABERDEEN, MISSISSIPPI.

IMPROVEMENT IN WATER-ELEVATORS.

Specificationl forming part of Letters Patent No. 120,714, dated November 7, 1871.

To all whom it may concern.-

Be it known that I, ALvEUs J. GLEMMoNs, of the city of Aberdeen, Monroe county, Mississippi, have invented an Improved VVater-Elevator, of which the following is a specification:

In the drawing, Figure l is a side elevation with part of the curb broken away; Fig. 2, a top view with part of the flange fm removed; and Figs. 3 and 4, sectional elevations of the bucket.

This invention relates to apparatus for drawing Water from a well by means of a bucket, chain, and chain-wheel 5 and it consists in a mechanism for automatically emptying the bucket and controlling the rotation of the chain-wheel by l means of a brake and catch.

Referring to the drawing, a is the bucket, the same having in its bottom a circular hole, and attached to the under side of its bottom a chute, the lower part c of which is hinged at one end so as to play between the sides c of the chute, forming, in fact, a valve, and having an orifice, el, the cover of which is a valve, e, hinged to the upper side of the valve c. A bail, j', extends upward from the valve c, through the circular hole in the bottom ofthe bucket a, to which bail is fastened the lower end of the chain g, that passes over the wheel l1,l mounted on the top of the curb A. A lever, t', jointed at one end to the top of the bucket, at one side thereof, passes through one of the links of the chain g, said lever being widened at each side of the chain to prevent the latter from slipping off it. The lever 'i is long enough to strike, as the bucket ascends, a rod,

j, placed across the curb beneath the shaft k of the chain-wheel, by which rod the lever z' is depressed, and that part of the chain between the lever and valve c loosened, which allows the valve o to fall, thus opening the hole in the bottom of the bucket, through which the water escapes, running over the valve o and between the sides c of the chute. The rod j at the same time swings the bucket to one side so far that the chute delivers water into the spout l. When the bucket, in descending, reaches the water in the well, the chain g loosens, the valve c falls, the valve e rises, and water enters the bucket through the orifice d. While ascending, the chain g draws the valve c tightly against the bottom of the bucket, and the water in the latter presses the valve e downward, closing the orifice d. The chain-Wheel h has a horizontal annular iiange, m. Alever, fn, pivoted to the top of the curb A, bears a wooden cushion, o, which enters the space inclosed by the flange on. By depressing the outer end of the lever n the cushion-o is forced against the inside of the ange m, thus operating as a brake. A pawl, p, secured to the pivot of the lever n, strikes the notched periphery of the wheel h whenever the brake p is let fall awayT from the flange on, thus preventing the rotation of the latter that would otherwise ensue.

l claim as my invention- The bucket a, combined with the chute o o', valves o e, chain g, and lever i, as described.
